Amazon Prime Day,A Male Friend Who Spins it Around the ecommerce bacchanal, is well underway, and if you want to make the most of it, you'll have to shop smart.

There are so many ridiculous deals out there — we're keeping track of the best of the best for you — but many of them won't drop until a predetermined time during the day.

These Lightning Deals will strike quickly and sell out fast, so you'll need to keep a close eye on them if you don't want to miss out. Thankfully, Amazon gives you the ability to track the products you're itching to buy, so that you won't miss out and get stuck on the Waitlist.

Here's how to track the best deals on Prime Day.

On a PC

On a PC, head over to Amazon using your web browser. Once you've logged into Prime, go to the Prime Day section of the site. Scroll on down to Upcoming Deals, where you'll be treated to a seemingly endless list of sales that will soon strike the site. Click on the "Watch this deal" button, and the product will be saved to a list in your account.

Scroll down further, and you'll be able to check out the deals you've selected to watch. There's not a ton of use here, since there are no desktop alerts, but it is helpful to keep everything in one place if you're planning on doing your Prime Day shopping on a computer.

On mobile

The easiest way to track your deal is on mobile the using Amazon app — unlike the browser version of the site, you'll be sent notifications directly to your smartphone. Instead of actively watching the screen and letting Prime Day dominate your life, you can kick back, relax, and let the deals come to you.

But before you do anything, make sure you turn on notifications within the app itself. If you don't set this up, you won't be able to get alerts when the sales are activated — so you can kiss those savings goodbye when the item sells out to all those other savvy Prime members out there.

When you open your app, head to the dropdown menu in the top left corner of the page. Tap Settings, then Notifications. From there, just swipe on Your Watched & Waitlisted Deals, as seen below.

After that, you're ready to shop. To stake out the top Lightning Deals before they strike, swipe over to the Upcoming section of the Prime Day menu.

As you swipe through the feed of specials and something catches your eye, just press on the "Watch this deal" button underneath the product image.

You can keep track of all the deals your watching by swiping over in the Prime Day menu. Products you select on a PC will show up here, too.

When a deal goes live, you'll be alerted via push notification — if you have the proper settings activated. If you want to win Prime Day, that's your first step. Otherwise, you'll spend the the sales extravaganza stuck on the waitlist.
